Steve, I shoot varmints past the effective range of the .204. Not knocking the .204, but it does nothing I want to do any better than the .22 caliber rifles can do it. The .220 Swift and .22-250 are about 1000x more useful than the .204. They are about 400 FPS faster as well. Supposedly the barrel life on the .204 will be a little better than the .22s, but I dont know anyone who has shot one enough to find out.
